The first 2 pictures are showing a moss with leafs that cannot be seen with the bare eye; looks like green velvet. Picture 1 shows a side view, 2 a top view which is more difficult to stack. The sample was found in an industrial environment.
Picture 3 shows the spore capsules of a moss with very small hair-like leafs. Noted mosses can have spore capsules althrough the year in Europe.
When taking picture 4 the photobleaching was (as always) an issue. I observed the bleaching started in the tips of the leafs and propagated to the inside. Meantime the leafs started to curl up. Within the first 20 seconds of exposure the object lost about 75% of its radiation. The same method was used as in the previous posts last 2 pictures: obscuring the mercury vapour lamp any time the camera sensor was not exposed.
Picture 5 is a better illustration of the "glow in the dark" effect of autofluorescence on a moss leaf, generated by the chlorophyl under UV excitation. The tip of that leaf is asking for a higher magnification...

All done with UV excitation, YOC-3 filter and 9x epi-objective (3,4,5), 7x (1,2).
Very nice.
